There is no such thing as a 1980 GT5S. The GT5S model was manufactured during 1984 with the first models offered as 1985 models.
It is possible the car is a GT5. There is a world of difference betwen the cars. E mail Claudia Lodi at DeTomaso to verify that the car is a real GT5. The price for that car, with all the usual caveats, is reasonable.
